Analog Modulation
Configuring the LF Output (Option UNT)
5. Press FM Off On.
You have set up the FM signal with a rate of 10 kHz and 75 kHz of deviation. The FM annunciator is
activated indicating that you have enabled frequency modulation.
Configuring the Low Frequency Output
1. Press the
LF Out hardkey.
2. Press
LF Out Amplitude > 3 > Vp.
3. Press
LF Out Off On.
You have configured the LF output signal for a 3 volt sine wave (default wave form) output which is
frequency modulated using the
Internal 1 Monitor source selection (default source).
To Configure the LF Output with a Function Generator Source
In this example, the function generator is the LF output source.
Configuring the Function Generator as the LF Output Source
1. Press
Preset.
2. Press the
LF Out hardkey.
3. Press
LF Out Source > Function Generator 1.
Configuring the Waveform
1. Press
LF Out Waveform > Swept-Sine.
2. Press
LF Out Start Freq > 100 > Hz.
3. Press
LF Out Stop Freq > 1 > kHz.
4. Press
Return > Return.
This returns you to the top LF Output menu.
Configuring the Low Frequency Output
1. Press LF Out Amplitude > 3 > Vp.
This sets the LF output amplitude to 3 Vp.
2. Press
LF Out Off On.
The LF output is now transmitting a signal using Function Generator 1 that is providing a
3 Vp swept- sine waveform. The waveform is sweeping from 100 Hz to 1 kHz.
